SEAL FOB BOX-OAR'DOORS,

7 Application filed March 14, 1923. SerialNo. 625,147.

The prime object of the invention is to provide a lock for sliding-doors of freight cars, particularly box cars wherein it is impossible to open the doors while the various cars comprising a train are coupled together.

A further object of the invention is to provide a lock for sliding box car doors, which can only be unfastened when the cars comprising the train are uncoupled and separated.

A still further object of the invention is to provide a lock and seal for box car doors which will prevent robbery of the cars during transportation of same.

And a still further object of the invention is to provide a look for box car doors of the character indicated, which is simple to operate when the cars have been uncoupled and separated, which is simple in construction,

durable, efficient for the purpose intended,

and one that can be manufactured and installed on box cars at a relatively low cost.

These and like objects of the invention will be better understood as the description follows and as is specifically pointed out in the appended claims.

Referringto the accompanying drawing which forms a part of this specification,

Figure 1 is a side elevation of a box car, with a portion of the side partly broken away to better illustrate the construction and operation of my car look.

Figure 2 is an enlarged section of the lock operating mechanism removed from the box car.

Figure 3 is an enlarged fragmentary section through the lock operating mechanism.

Referring to the accompanying drawing in detail, like characters will be used to designate like parts in the different views.

In the drawing, the numeral 1 indicates a box car, which comprises one portion of a train. The car 1 is provided with the usual sliding door 2 having a; hook catch 3 on one side of same.

Supported from the roof of the car by means :of brackets 4 is a horizontal "shaft I 5,

which is rounded for; the greater portion of its length and provided with a square end as at 6. On the opposite end of the shaft 5 is mounted a wheel 7. I f

A drum 8 supported from the roof of the -car by means of brackets 9 is positioned directly in the path of the shaft 5, which passes through a central passageway 10 formed'in the member 8. A cable 12, which can be in the form of a chain as shown in the accompanying drawing, is attached to the drum by means of a screw eye 13 and the opposite end of the chain or cable 12 is attached as at 14 to a pivoted lever 15,'one end of which is provided with a hook 16 for engagement gith the hook catch carried by the box car oor. 1

When the car 1 is coupled to a car in frontof same, and the door is in a closed position, it is absolutely impossible to open the door, as before the door can be opened, it is necessary to slide the rod 5 forwardly to bring the square portion 6 into engagement with the bore 10 a'nd upon rotation ofthe wheel 7 the chain or cable 12 is wound on the drum 8 causing the lever 15 to swing on its pivot and the hook16 to disengage from the hook the square bore 10 of'the drum 8. Therecatch carried by the door, thus permitting the door to be moved to an open position.

In view of the foregoing description of my invention taken in connection with the accompanying drawing, it-is thought that any further explanation as to the construction, operation, and objects of the invention is unnecessary.

While I have shown and described thepreferred form of my invention, I realize that various minor changes may be resorted-to,

without departing from the spirit and scope of the invention as claimed, and therefore, I

do not wish to limit myself to the exact details of construction shown, nor to the combination and arrangement of parts.

What I claim as new and desire to secure by Letters Patent is: p

1. In a lock for box car doors, a horizontal shaft, a drum positioned on said shaft, a locking lever, means for o connecting said drum with said locking lever,--zind means mounted on one end of said shaft 'for -rotating the same to move the looking lever to an inoperative position. r

2. In a lock for boxcar doors, a shaft having a square end, a drum mounted on'said shaft and provided with a square central bore, a pivoted locking lever adapted to be normally held in engagement With-the boxcar door,-means for connecting said drum and locking lever, and means for moving shaft forwar dly to hring 'said" square portion into engagement with said drum for JAMES-EMMET MQINNIS.
